Objective: This study aims to examine factors associated with suicidal ideation among people with opioid dependence and to explore whether these factors are gender-specific.Methods: Cross-sectional data were collected among long-term opioid-dependent individuals ( n = 176; 46.0% women). Lifetime histories of suicidal ideation were measured using the Composite International Diagnostic Interview, and additional data were collected regarding sociodemographic characteristics, drug use, health, and adverse life events. Multivariable logistic regression was used to determine the relationships between these variables and suicidal ideation for the full study sample and separately for women and men to explore the potential role of gender.Results: A total of 43.8% ( n = 77) of participants reported a lifetime history of suicidal ideation. Among those with suicidal ideation, 49.3% were women and the overall average age of first ideation was 19.82 years (SD, 11.66 years). Results from multivariable analyses showed that a history of depression, anxiety, and childhood emotional neglect and the number of lifetime traumatic events were significantly associated with higher odds of suicidal ideation. The gender-based analysis suggested that histories of depression and anxiety remained independently associated with lifetime suicidal ideation among women, whereas for men, childhood emotional neglect and the number of lifetime potentially traumatic events were independently associated with lifetime suicidal ideation.Conclusions: This study offers a critical first step to understanding factors associated with suicidal ideation among long-term opioid-dependent men and women and the potential importance of gender-sensitive approaches for suicidal behavior interventions. These data inform further research and clinical opportunities aiming to better respond to the psychological health needs of this population. [ABSTRACT FROM AUTHOR]

Objective: Extensive exposure to prescription-type opioids has resulted in major harm worldwide, calling for better-adapted approaches to opioid agonist therapy. The authors aimed to determine whether flexible take-home buprenorphine/naloxone is as effective as supervised methadone in reducing opioid use in prescription-type opioid consumers with opioid use disorder.Methods: This seven-site, pan-Canadian, 24-week, pragmatic, open-label, noninferiority, two-arm parallel randomized controlled trial involved treatment-seeking adults with prescription-type opioid use disorder. Participants were randomized in a 1:1 ratio to treatment with sublingual buprenorphine/naloxone (target dosage, 8 mg/2 mg to 24 mg/6 mg per day; flexible take-home dosing) or oral methadone (≈60-120 mg/day; closely supervised). The primary outcome was the proportion of opioid-free urine drug screens over 24 weeks (noninferiority margin, 15%). All randomized participants were analyzed, excluding one who died shortly after randomization, for the primary analysis (modified intention-to-treat analysis).Results: Of 272 participants recruited (mean age, 39 years [SD=11]; 34.2% female), 138 were randomized to buprenorphine/naloxone and 134 to methadone. The mean proportion of opioid-free urine drug screens was 24.0% (SD=34.4) in the buprenorphine/naloxone group and 18.5% (SD=30.5) in the methadone group, with a 5.6% adjusted mean difference (95% CI=-0.3, +∞). Participants in the buprenorphine/naloxone group had 0.47 times the odds (95% CI=0.24, 0.90) of being retained in the assigned treatment compared with those in the methadone group. Overall, 24 drug-related adverse events were reported (12 in the buprenorphine/naloxone group [N=8/138; 5.7%] and 12 in the methadone group [N=12/134; 9.0%]) and mostly included withdrawal, hypogonadism, and overdose.Conclusions: The buprenorphine/naloxone flexible model of care was safe and noninferior to methadone in reducing opioid use among people with prescription-type opioid use disorder. This flexibility could help expand access to opioid agonist therapy and reduce harms in the context of the opioid overdose crisis. [ABSTRACT FROM AUTHOR]

• Safer supply pilot programs face several inner and outer implementation challenges in Canada. • It is essential to provide adequate sustainable support to pilot programs during their implementation. • Policymakers should ensure that appropriate medications are available to meet the needs of clients in safer supply programs. Canada is experiencing an unprecedented drug toxicity crisis driven by a highly toxic unregulated drug supply contaminated with fentanyl, benzodiazepine, and other drugs. Safer supply pilot programs provide prescribed doses of pharmaceutical alternatives to individuals accessing the unregulated drug supply and have been implemented to prevent overdose and reduce related harms. Given the recent emergence of these pilot programs and the paucity of data on implementation challenges, we sought to document challenges in their initial implementation phase. We obtained organizational progress reports from Health Canada, submitted between 2020 and 2022 by 11 pilot programs located in British Columbia, Ontario, and New Brunswick. We analyzed the data using deductive and inductive approaches via thematic analysis. Analyses were informed by the consolidated framework for implementation research. We obtained 45 progress reports from 11 pilot programs. Six centres were based in British Columbia, four in Ontario, and one in New Brunswick. Four overarching themes were identified regarding the challenges faced during the establishment and implementation of pilot programs: i) Organizational features (e.g., physical space constraints, staff shortages); ii) Outer contexts (e.g., limited operational funds and resources, structural inequities to access, public perceptions); iii) Intervention characteristics (e.g., clients' unmet medication needs); and iv) Implementation process (e.g., pandemic-related challenges, overly medicalized and high-barrier safer supply models). Safer supply pilot programs in Canada face multiple inner and outer implementation challenges. Given the potential role of safer supply programs in addressing the drug toxicity crisis in Canada and the possibility of future scale-up, services should be well-supported during their implementation phases. Refining service provision within safer supply programs based on the feedback and experiences of clients and program administrators is warranted, along with efforts to ensure that appropriate medications are available to meet the clients' needs.

Background: Opioid-dependence is a chronic relapsing disorder. Histories of physical, sexual, and emotional abuse are prevalent among long-term opioid users. While perceived abuse in health care has been linked to histories of abuse in other populations it has not been investigated among long-term opioid users. Objective: To determine factors associated with perceived abuse in health care among a sample of long-term opioid users. Methods: Gender Matters in the Health of Long-Term Opioid Users (GeMa) was a descriptive cross-sectional study. Participants (n = 175) answered questions on health, drug use, treatment history, and victimization. A multivariable model of perceived abuse in health care was built using logistic regression. Results: Half of participants (n = 88) reported perceived abuse in health care in lifetime with no gender differences. Histories of abuse, physical, and psychological health problems, and health care access were more prevalent among those reporting perceived abuse in health care compared to those not reporting such experiences. Multivariable analysis showed that more methadone maintenance treatment attempts in life, prescribed psychiatric medication in life, and having higher childhood emotional abuse scores were independently associated with perceived abuse in health care. Among all childhood neglect and abuse types measured, emotional abuse was the only significant predictor. Conclusions: A high prevalence of lifetime perceived abuse in health care (50%) was reported, along with extremely high childhood abuse and neglect scores. Consideration of these variables by health care and service providers is extremely important to improving patient perceptions of care, and ultimately health and treatment outcomes among opioid-dependent people.
